missing folders from a shared folder

I think the only solution is to be patient))) At the time of the MacBook update, this MacOS operating system "saved" data from Dropbox somewhere in its memory. So it was "like" deleted when looking in DropBox. AFTER MacOS has finished updating and indexing the files, this operating system has returned them to a directory location on the MacBook. And from the directory in the MacBook, the data is then synchronized with the directory in DropBox. The problem arises when the directory in DroPbox is shared by, for example, 2 users who are updating a MacBook. Updating the MacBook, indexing the data in the MacBook and subsequent synchronization takes at least 12 hours according to my estimation. Recommendation if there are multiple members of the shared directories in DropBox that have MacOS at the same time: Update your MacBook gradually and individually. A member of a shared directory will always wait until the update, indexing, and synchronization from the first participant is complete (1 day). Do not use DropBox at that time. IT'S ONLY MY OPINION BASED ON EXPERIENCE - NO WARRANTY.

Thanks @tomasewski that experience sounds very similar to mine. We ran the MacOS 14 update on a couple of computers connected to our office DropBox at the same time and had the same unfortunate issue with our files as you had with yours. 

Subfolders in a shared (2 members including me) Dropbox Folder are disappearing!    Three days ago, a number of critical subfolders disappeared from my local as well as online Dropbox account, but were still appearing in the other person's local Dropbox.    Today, subfolders also disappeared from the same folder the other user's local Dropbox.    Neither of us have deleted any folders, and in fact the disappearance from my local and online Dropbox came after 30 days of no use of my computer (Mac 13.5.1).   The other user has been using Dropbox almost daily.   The missing folders do no appear in deleted folders or anywhere else.   What is going on, and how to recover- "Rewind"?    

Sorry to hear about this, SVC-2.

Have you checked your events page to see if you can find any events related to those folders?

Hey Bridewell, sorry to hear about this.

I would suggest checking your events page, to see if you can find any events related to that shared folder.

Hi Hannah,

In our case the event was noted on the Events page. Can you clarify how this helps us, or why it matters? For example, is there a way to reverse an event that was not user initiated? I did not see that option. Also is there an update from Dropbox on why there errors are occurring?

Thanks for your help!

Depending on the event, it might be possible to reverse it.

What does it say about the particular folder?

It says Mass Data move. It doesn't give an option to reverse or undo the action.
